DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In order to further appreciate the characteristics and technical contents of the instant disclosure, references are hereunder made to the detailed descriptions and appended drawings in connection with the instant disclosure. However, the appended drawings are merely shown for exemplary purposes, rather than being used to restrict the scope of the instant disclosure.

Please refer to FIG. 1, which shows a supporting stand 100 for multiple screens of the instant disclosure. The supporting stand 100 comprises a frame 1 and a movable module 2. The frame 1 is used for disposing on a working surface 200 (e.g., wall surface or surface of a cart support). The movable module 2 is used for supporting two screens 300.

As shown in FIG. 2, the frame 1 has a strip-like shape and defines a longitudinal direction C. The frame 1 has a plate 11 and a track module 10 having two tracks 12 respectively extended from opposite sides of the plate 11. The movable module 2 has two movable units 20 respectively corresponding to the two tracks 12.

Each track 12 has a lateral surface 121 and two restricting surfaces 122 concavely formed thereon. In other words, the lateral surfaces 121 of the tracks 12 are arranged on opposing sides of the frame 1. Moreover, the restricting surfaces 122 of opposite tracks 12 are respectively formed along a first direction and a second direction (i.e., the directions pointed by the right arrow and the left arrow in FIG. 1) on the lateral surfaces 121.

Specifically, the longitudinal direction C, the first direction, and the second direction in this embodiment are parallel to each other. Thus, the relationships related to the first direction and the second direction in the following description are described or defined by the longitudinal direction C.

The movable units 20 are disposed on respective tracks 12. The two tracks 12 are identical to each other, and the movable units 20 are identical to each other as well. In addition, the tracks 12 and the movable units 20 are arranged symmetrically with respect to the plate 11. Thus the following description is provided for one track 12 and the corresponding movable unit 20.

As shown in FIGS. 3 and 4, each restricting surface 122 has a pair of first restricting segments 1221 and a second restricting segment 1222 formed inwardly on the lateral surface 121. The first restricting segments 1221 are connected between the lateral surface 121 and the second restricting segment 1222. The first restricting segments 1221 are parallel to each other, and the cross-section of the second restricting segment 1222 perpendicular to the longitudinal direction C is approximately C-shaped.

More specifically, for the cross-section perpendicular to the longitudinal direction C of each restricting surface 122, the largest separation distance between any two points of opposing sides of the second restricting segment 1222 is greater than the largest separation distance between the first restricting segments 1221. In other words, each restricting surface 122 defines a restricting trough 1223. As shown in FIG. 4, the cross-section perpendicular to the longitudinal direction C of the restricting trough 1223 is approximately T-shaped, but not limited thereto. For example, the restricting trough 1223 can be dovetailed as shown in FIG. 6.

The track 12 has a plurality of positioning holes 1211 concavely formed on the lateral surface 121, and the positioning holes 1211 are arranged between the two restricting troughs 1223 and vertically spaced along the longitudinal direction C.

As shown in FIG. 2, each movable unit 20 has a sliding component 21, a pivoting assembly 22, and a fixing component 23. The fixing component 23 in this embodiment is a screw, but not limited thereto.

As shown in FIG. 3, the sliding component 21 has a pivoting portion 211, two sliding blocks 212, and a fixing plate 213. The pivoting portion 211 has a pivoting hole 2111 concavely formed from the top surface thereof along the longitudinal direction C. The lateral surface 2112 of the pivoting portion 211 conforms in shape (flushed) to the lateral surface 121 of the corresponding track 12. The two sliding blocks 212 are formed on the lateral surface 2112. Moreover, the lateral surface 2112 of the pivoting portion 211 and the lateral surface 121 of the track 12 in this embodiment are planar, but not limited thereto.

The cross-section perpendicularly to the longitudinal direction C of each sliding block 212 is T-shaped (as shown in FIG. 5) or dovetailed (as shown in FIG. 6) and is approximately identical to the cross-section of the restricting trough 1223. The outer surface parallel to the longitudinal direction C of the sliding block 212 is defined as a contacting surface 2121. More specifically, the contacting surface 2121 has a pair of first contacting segments 2122 and a second contacting segment 2123 arranged outwardly from the lateral surface 2112.

The fixing plate 213 is extended from the bottom edge adjacent to the lateral surface 2112 of the pivoting portion 211. The fixing plate 213 has a penetrating hole 2131 arranged below the two sliding blocks 212.

As shown in FIG. 2, the pivoting assembly 22 has a plurality of pivoting components 221 pivotally connected. One of the pivoting components 221 of the pivoting assembly 22 is pivotally engaged to the pivoting hole 2111 of the pivoting portion 211 of the sliding component 21, and the other one is used for supporting the screen 300.

Based on the above, when the two movable units 20 are set on the frame 1, the sliding blocks 212 of the two sliding components 21 are respectively disposed in the restricting troughs 1223 of the two tracks 12, and the contacting surfaces 2121 respectively contacting the restricting surfaces 122. That is to say, the first contacting segments 2122 respectively contact the first restricting segments 1221, and the second contacting segments 2123 respectively contact the second restricting segments 1222. Thus, the contacting surfaces 2121 of the two sliding components 21 respectively contact the restricting surfaces 122 of the two tracks 12 for enabling the two sliding components 21 to move respectively along the first direction and the second direction.

Subsequently, when the two movable units 20 are respectively adjusted at two positions and the penetrating hole 2131 of each sliding component 21 is aligned to one of the positioning holes 1211 of each tracks 12, the fixing components 23 are respectively passed through the penetrating holes 2131 and the corresponding positioning holes 1211 such that the two movable units 20 are respectively fixed at the two positions. Besides, the fixing components 23 can be respectively abutted to the lateral surfaces 121 of the tracks 12 for pressing the sliding components 21 toward the corresponding tracks 12 to achieve the fixing effect between the sliding components 21 and the corresponding tracks 12. Moreover, the two movable units 20 can be respectively position on the frame 1 at different heights (as shown in FIG. 7).

Besides, the supporting stand 100 can be used for supporting three screens 300. As shown in FIG. 8, the track module 10 further has an auxiliary track 12′. Specifically, the structure of the auxiliary track 12′ is approximately identical to the tracks 12, but the auxiliary track 12′ has a restricting surface 122′ extended along a third direction (i.e., from top to bottom in FIG. 8) and is disposed on the center portion of the plate 11.

Moreover, the movable module 2 further has an auxiliary movable unit 20′ corresponding to the auxiliary track 12′. In FIG. 8, the auxiliary movable unit 20′ is illustrated by an auxiliary sliding component 21′, but is not limited thereto.

Specifically, the structure of the auxiliary movable unit 20′ is approximately identical to the movable unit 20. The auxiliary sliding component 21′ has a contacting surface 2121′ corresponding to the restricting surface 122′.

Thus, the auxiliary movable unit 20′ is movable along the third direction by the contacting surface 2121′ of the auxiliary sliding component 21′ contacting the restricting surface 122′ of the auxiliary track 12′. The longitudinal direction C, the first direction, the second direction, and the third direction in this embodiment are parallel to each other, but not limited thereto.

Based on the above, the supporting stand for multiple screens of the instant disclosure uses the contacting surface of each sliding block matching to the restricting surface of each track for enabling the contacting surfaces of the sliding blocks to be moved respectively along the restricting surfaces of the tracks. Thus, the movable units of the movable module can be respectively adjusted to the desired positions for achieving different user's demands.

Furthermore, the movable units of the movable module can be respectively fixed at desired positions by co-operating the fixing components with the positioning holes of the tracks, so that the supporting stand can be applied to different operating situations.
